TORQUE CONVERTERS | CAConversions | All You Need to Know About Torque Converters

A torque converter is a fluid coupling device that is commonly used in automatic transmissions of vehicles. Its primary function is to transmit power from the engine to the transmission, allowing the vehicle to move forward or backward. The torque converter allows the engine to keep running while the vehicle is stationary or moving slowly, without the need to manually engage and disengage the clutch as in a manual transmission. Here's how a torque converter works: Impeller: The impeller is connected to the engine's crankshaft. As the engine runs, it spins the impeller, which in turn creates a flow of transmission fluid inside the torque converter. Turbine: The turbine is connected to the input shaft of the transmission. As the fluid from the impeller flows onto the turbine blades, it causes the turbine to rotate. Stator: The stator is situated between the impeller and the turbine and is mounted on a one-way clutch. Its primary purpose is to redirect the fluid flow so that the torque converter can be more efficient. It helps to redirect the fluid in a way that enhances torque multiplication. Lockup Clutch: In many modern torque converters, there is a lockup clutch that can mechanically connect the impeller and the turbine. This is typically engaged at higher speeds to reduce slippage, increase efficiency, and improve fuel economy. One of the key advantages of a torque converter is its ability to provide torque multiplication, especially at low speeds. This means that the torque output at the turbine can be higher than the torque applied at the impeller. This helps in providing sufficient power for accelerating heavy vehicles from a standstill. However, torque converters also have some inherent efficiency losses due to fluid slippage, which can lead to decreased fuel efficiency compared to manual transmissions or newer automated manual transmissions (AMTs) that use a dry clutch. To mitigate this, many modern vehicles with automatic transmissions employ various technologies such as lockup clutches and continuously variable transmissions (CVTs) to improve efficiency. In summary, a torque converter is a critical component in automatic transmissions, allowing for smooth power transfer and enabling a vehicle to change gears without manual intervention.
